New to solar? No problem. We'll ask a few simple questions - one at a time - then show you what a system could cost, how much you could save, and when it would pay for itself.
This gives us a sensible starting point for how much electricity you use in a year. Roughly is fine.
Solar saves you the most when you use the electricity your panels make, rather than sending it back to the grid. A rough idea of your yearly usage lets us estimate that. A typical 3-bed home near here uses around 3,700 units (kWh) a year.
South-facing panels make the most electricity. East or west still work well. Not sure? Pick "Not sure" and we'll use a fair average.
Check a maps app, or use the compass on your phone at the front of the house. The direction the main roof slope points is what matters. East/west roofs typically make only about 15-20% less than a perfect south-facing one.
Shade from trees, chimneys or nearby buildings lowers how much your panels make, especially around midday.
Not necessarily. A bit of shade lowers output rather than stopping it, and modern setups can use panel-level optimisers so one shaded panel doesn't drag the rest down. Heavy all-day shade is the real problem - we'll assess it properly on a survey.
Drag the slider. Most homes fit 6-14 panels - we'll confirm what actually fits when we survey your roof.
kWp (kilowatt-peak) is the size of the system - bigger number, more electricity. A typical 3-bed home has around 4-4.5 kWp, which is roughly 10 panels over 20-30 m² of roof.
A battery stores the solar you don't use in the day so you can use it in the evening - more savings, but more cost.
A battery means you rely on the grid far less, so you save more each year. It does add cost and can lengthen the payback a little unless you're on a smart tariff - but it also gives you backup power in a cut. Happy to talk it through.
If the house is busy 9-5, or you run the washing and dishwasher during the day, you'll use more of your solar directly - which saves more.
Using solar as it's made is worth more than exporting it - you avoid paying ~25p a unit to buy electricity, but only earn ~12p for the surplus you export. So the more you use during the day, the more you save. A battery helps if the house is empty 9-5.
Optional. Charging an EV at home makes solar even more worthwhile. We'll add a note if so.
These are friendly estimates based on typical local figures, not a fixed quote. Your exact numbers depend on your roof, your tariff and your habits - which is what a proper survey confirms.
